I will share a few facts about an Irvin Muchler in our family - our Irvin Muchler was born on 31 Jan 1943 in Pennsylvania or New Jersey. He was the second of six children, two sisters, Caroline and Ruth, and three brothers, Benny, Bill and Raymond. His mother was a Parsons from Wilkes-Barre, PA. Camden, Pennsauken, Berlin and Delair are all areas where his family or other relatives and friends lived. Some of his family members are buried in Lumberton.
Irvin's first wife was Louise ?. They were married for a few years. First child was a girl, she died after only a few months of crib death. Other children followed, a daughter, Barbara, Irvin Jr. and Michael. I believe that he installed bathroom/kitchen tile for his lively hood. When he was in his teens, he was hit by a car. His leg was pretty torn up and he walked with a limp for the rest of his life. He had a second wife, Marylee. Irvin died on 7 Feb 2007 in PA.
There definitely seem to be similarities - maybe this Irvin and yours are one and the same?
